Definitions
- the present invention relates to UV absorbing compositions, in particular to UV absorbing composition including a surface modified inorganic oxide dispersed in particulate form.
- modified zinc oxide as the UV attenuating oxide, however the invention also extends to other inorganic oxides including titanium dioxide and iron oxide.
- Zinc oxide scatters some wavelengths of light and absorbs other selected wavelengths of light. It exhibits very strong absorption at wavelengths just short of the visible spectrum. It is a strong UVB absorber at the 210-320 nm wavelength and also at the UVA 320-840 nm wavelength. At wavelengths longer than 370 nm, protection is provided by scattering and at wavelengths shorter than 370 nm, protection is achieved predominantly by absorption. Zinc oxide exhibits a strong semi-conductor absorption in the ultraviolet region. The optimum size of a zinc oxide particle for attenuation of the ultraviolet radiation is less than 0.06 ⁇ m for the wavelength range 300 - 400 nm. Absorption is the dominant mechanism for attenuation of ultraviolet radiation in the wavelength range of 300 - 400 nm.
- Zinc oxide has been used as a white reflective pigment (particles size 1.0 - 20 ⁇ m) and as a UV absorber (particles 0.3 - 5 ⁇ m) for many years.
- the earliest form of presentation of zinc oxide as a sunscreen agent is a pigmented cream which is used to protect various parts of the exposed body, particularly the nose. Although this zinc oxide cream has its place, the conspicuous nature of the cream when on the skin reduces its cosmetic appeal significantly. Attempts at turning a disadvantage to advantage has led to recent variations of the zinc oxide cream in which a coloured pigment is used to produce a brightly colour cream such as blue, red, yellow or green cream. Such modifications, although popular particularly with the young, have limited cosmetic appeal to the more general population.
- UV attenuating substance be invisible on the skin with any colour variation in the sunscreen formulation being adjusted to achieve a desired cosmetic effect.
- Prior art zinc oxide formulations are also limited in terms of the amount of zinc oxide that could be mixed into the formulation (up to about 10% by weight) which limits the blockout effect of the sunscreen.
- various wetting agents, in combination with anti-settling agents have been used, this effectively decreasing the amount of UV active that can be included in the formulation, adding to the cost of manufacture and increasing the risk of an adverse skin reaction.
- freshly made zinc oxide can absorb carbon dioxide which leads to the formation of carbonates on its surface. This absorption of carbon dioxide thus inhibits the UV absorbing properties of the zinc oxide.
- the present invention provides, in one aspect, a process for producing a dispersion of particles of an inorganic oxide selected from zinc oxide, titanium dioxide or iron oxide in a liquid, the process including comminuting the oxide, preferably in an amount of from 10 to 95% by weight of the final dispersion, in the presence of the liquid to produce smaller particles with fresh cleavage surfaces
- the liquid is selected from the group consisting of alcohols,esters, hydrogenated esters and polymers containing available hydroxyl group(s) or hydrogen group(s), preferably selected from the groups consisting of dioctyl phthalate, glycerol mono-oleate, glycerol mono-stearate, isopropy myristate, diethyl phthalate, propylene glycol dicaprylate/caprate, glycerol tricapylate/caprate, methyl laurate, propylene glycol, methyl oleate, dioctyl adipate and mixtures thereof, and wherein the
- zinc oxide crystals when zinc oxide crystals are comminuted during the process of the invention, they produce smaller particles with fresh cleavage surfaces, these surfaces when produced by comminution in the liquid, bond to available hydrogen ion and/or oxygen ion to form zinc oxide which is both encapsulated and bonded to a film of the liquid. This gives a very stable product which does not aggregate, agglomerate or settle out to a hard layer.
- the oxide is comminuted to a particle size in the range of less than 10 ⁇ m and preferably in the range of from 0.04 to 0.5 ⁇ m and more preferably the particles are comminuted in the liquid from a particle size of 0.2 ⁇ m to 10.0 ⁇ m to provide a particle size in the range of 0.04 to 0.5 ⁇ m.
- the component containing available hydrogen ion and/or oxygen ion may be a substance or compound having one or more hydroxyl groups or hydrogen groups.
- the liquid is selected from one of an alcohol, ester, hydrogenated ester or polymer containing hydroxyl group(s) or hydrogen group(s) or mixtures of two or more of the foregoing.
- suitable liquids may be selected from the group consisting of dioctyl phthalate, glycerol mono-oleate, glycerol mono stearate, isopropyl myristitate, diethyl phthalate, propylene glycol dicaprylate/caprate, glycerol tricaprylate/caprate, methyl laurate, methyl oleate and dioctyl adipate.
- the liquid in which comminution takes place is substantially free of water. More preferably the liquid is free of water.
- Comminution of the oxide may be carried out by milling. Milling may be achieved by any suitable method. Milling may be carried out using a ball mill, or other intensive mill such as a bead mill, attritor mill or sigma mixer.
- the process of the invention is carried out by adding the oxide in the particulate form to the liquid whilst milling occurs although the oxide may be combined with the liquid and the mixture milled.
- the initial particle size of the oxide may be in the range of about 0.5 ⁇ m to 10.0 ⁇ m.
- the zinc oxide used in the present invention may be crystalline zinc oxide. Amorphous porous zinc oxide is preferred where a very small comminuted particle size is desired as it is easier to mill down.
